Abstract: 1,045,741. Wigs. REID-MEREDITH Inc. March 28, 1963 [Oct. 30, 1962], No. 12277/63. Heading A4V. [Also in Division D1] An artificial hair piece (Fig. 4, not shown) comprises a knitted cover A which during knitting has filaments B, e.g. natural hair or "Dynel" (Registered Trade Mark), at least six inches long looped into it to extend from one side. A tow of 24 denier monofil "Dynel" is dyed, cut into nine inch lengths and blended to form a sliver 30 which is wound on a reel or drum 31 Fig. 8, (not shown). The sliver is then passed through the feed rolls 32, 33 of card mechanism 34 where a lickerin 35 introduces the filaments to card cylinder 36 Fig. 9 (not shown). Projections 38 on a belt doffer 37 doff the filaments at 41 on to the needles 39 of the knitting machine assisted by air from ducts 40a. The fabric is knitted on a Wildman Jacquard machine with ten needles per inch from which every other needle is removed. The base of the hair piece is knitted from nylon "Acrilan", (Registered Trade Mark) or "Lycra", (Registered Trade Mark). The tubular fabric is cut and a section is placed over a forming station where a die 55, Fig. 12 (not shown) forms a cavity to fit the head. This section is then turned inside out and tapes some of which may be resilient are then applied so that the hair piece will grip the head. Excess fabric is removed.

A first member 10, e.g. a storage cell casing, including heat-weldable plastics side walls 11 which terminate in a rim 31 is secured to a second member 19, e.g. a lid, including heatweldable plastics side walls 26a which terminate in a rim 30 having a configuration corresponding to that of the rim 31 by disposing the members 10, 19 in spaced relationship with the rims 30, 31 facing each other and in registry, heat soften-  ing the rims 30, 31 by a member 32 disposed between but spaced from the rims, removing the member 32 from between the rims, and contacting the heat softened rims under pressure whilst maintaining the registry of the rims, at the same time mechanically supporting the side walls of at least one of the members 10, 19 so as to prevent lateral deformation thereof, whereby the members 10, 19 are welded together. The casing 10 contains electrode plates and separators, the positive electrode plates being secured by lugs 15 to a post 13 and the negative plates to a post 14. The lid 19 is provided with apertures 28, 29 to receive the posts 13, 14 and an opening 24 for filling the cell with electrolyte. A moulded plastics strengthening piece 18 is placed inside the casing 10 and is provided with apertures 21, 22 for the posts 13, 14 and a shaped baffle 23 which passes between the lugs 15. Apertures 25 are provided in the baffle 23 for the passage of the electrolyte. To effect the welding, a metal strengthening piece 36 having a sharp edge 37 is placed around the walls 11 near the rim 31. A metal plate 32, provided with electrical heating resistors and a thermostat, is positioned as shown in Fig. 4, equidistant from the rims 30, 31 if they are made of the same material, e.g. polyamide. The plate 32 heats the rims 30, 31 by radiation or convection and is then removed and the rims 30, 31 are pressed together. Two beaded protrusions 38, 39, Fig. 6 (not shown), are formed by the welding and the external protrusion (38) may be cut off by the edge 37 by pushing the casing through the frame 36. If the easing 10 and the lid 19 are made of polyamide, they may be heated in a drying oven at 70 C. for 20 hours, prior to welding, to remove all traces of moisture.

Abstract: 1,227,285. Electric circuit-breakers. CONTINENTALE ET GARNIER. 21 Aug., 1969 [27 Aug., 1968; 7 Aug., 1969], No. 41759/69. Heading H1N. A circuit-breaker employs a "floating lever", 1 one end of which can engage a stop 8a that moves clear when a fault arises and which controls the movable contact member 2 to cooperate with a fixed contact 4 as a toggle linkage formed by an operating lever 15 and connecting link 17 is operated with the connecting link 17 coupled to the lever 1 by a pivot pin 19 movable in a curved slot 20 in the lever 1. A main spring 7 biases the contact member 2 for movement limited by a stop 6 about a pivot 3 in the lever 1 which is thus biased in a clockwise direction about the pin 19 which extends between guide surfaces 22, 23 of the circuit-breaker housing 5. In the closed position shown in Fig. 2 the force of the spring 7 maintains the toggle joint formed by members 19, 17 over centre against the bias of a resetting spring 21. Under fault conditions a bimetal strip 12 or the armature 14 of an electromagnet 13 may move a lever 8 away from a stop 11 so that the stop 8a on the lever 8 disengages the end of the lever 1 which will then rotate about the pin 1 and as the contacts 2, 4 open the lever 1 is guided by a pin 24 thereon engaged in a housing slot 25 so that the pin 19 moves between surfaces 22, 23 and the lever is rotated to an angle at which the pin moves along the slot 20 before the mechanism is reset in the circuit open position (Fig. 1, not shown). A multipole circuit breaker may have circuitbreakers as described above with additional cam members (Figs. 7 and 8, not shown) coupled together and located so as to be rotated by any lever 1 which is released from its cooperating stop 8a and to rotate to move the levers 8 of the other circuit-breakers.

Abstract: 1,234,095. Photo-electric thread supervision. W. REINERS. July 29, 1968 [July 27, 1967], No.35997/68. Heading G1A. [Also in Division H3] The invention relates to a device for switching off a textile machine in the absence of a thread (e.g. due to breakage, the end of a spool or cutting of the thread), in which the movement of the thread produces an alternating voltage which is amplified, rectified and then used to charge a capacitor which controls the machine switch. According to the invention operation is speeded by emphasizing the higher frequencies, by limiting the alternating signal amplitude and by using a rectifier of the full wave type. As shown, the photoelectric cell 1 receives light from a path including a very short length of its thread so that the relatively high frequency voltages due to vibration and projecting fibres are produced. These are passed through an amplifier which emphasizes the high frequencies to a full wave rectifier 21, a storage capacitor 22 and a switch controlling transistor 24. The capacitor prevents short spurious pulses from operating the switch. Its discharge time may however be short; firstly because the full wave rectifier provides a restoring charge at each half cycle, secondly because the amplifier selects the higher frequency components of the alternating wave and thirdly because the amplifier is designed to limit the alternating signal amplitude to a low level so that even on a strong signal the charge on the capacitor is not large. The frequency selection is effected by a circuit 14, 15, 6 which provides negative feedback at lower frequencies and positive feedback at higher frequencies. Diodes 26 provide for control of the switch-off of the machine by other circuits. The photo-electric detector 1 may be replaced by one of the capacitive or mechanically vibrating type and thread guides are placed close to each side of the detector to confine thread vibrations to the higher frequencies.
